Product Overview
TB-500 (Ac-LKKTETQ) is a synthetic N-terminally acetylated heptapeptide corresponding to amino acid residues 17–23 of human thymosin β4 (Tβ4). The peptide sequence is Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (Ac-LKKTETQ).
TB-500 is structurally distinct from full-length thymosin β4. Published analytical studies have identified the N-terminally acetylated 17–23 fragment as the characteristic peptide associated with TB-500. It is used as a research compound in laboratory studies involving peptide characterization, metabolism, actin-related biology, cellular migration, and analytical method development.
